SONY Walkman 64GB ZX Series NW-ZX707 : High-end streaming WALKMAN

Product Description

The NW-ZX707 is the 64GB model in Sony's ZX Series Walkman line, built around the S-Master HX full-digital amplifier, independently developed for Walkman hardware. Sony positions the ZX Series as inheriting technology from its Signature Series (WM1) flagship Walkman line.

This is a genuine Japan-market unit imported by wafuu.com. Sony's Japan-spec units run in high-gain mode with full rated output power (50mW+50mW unbalanced / 230mW+230mW balanced into 16Ω); units sold through some other regions' retail channels are capped to a lower-output gain mode.
